Meta policy watcher should be leader protected and update backend #55
Currently the policy meta engine will not run if the Consul backend is enabled due to the legacy way in which the storage was built. In addition the meta policy watcher is not leader protected and so multiple Sherpa servers will process job meta changes.
The meta policy engine should be updated to allow it to run in conjunction with the Consul storage backend. The meta policy engine should also be leader protected, so that only one Sherpa server processes updates.
